Pm-1228vf-lb

The tool holders bottom out on the compound slide. That's what keeps them from being able slide down low enough to line up with the center of your work.

You could have 50 thousandths ground off the bottom of each tool holder so it would hold the tool lower. Most people have multiple tool holders, so any time you get a new one, you'd have to modify it. The simple solution is to lower the surface the tool holder is bottoming out on.
 
"BXA is 5/8" tooling."
Ah, I guess I was off by one size. I see lots of "10mm" import mini-lathe tooling which is about .40", which I have to assume is what our lathe is designed around. Lame, but sort of makes sense considering where they are built. As a work around, I suspect you could tilt the front of the tool down with shims at the tail. So long as you aren't getting down to small radii, the cutting angle would remain constant (and its change may not end up mattering that much depending on the task)

"Condolences on the shipping damage. Not a good feeling."
Eh, I buy gun parts kits; I'm used to it, now. The ebay turntable was WAY worse, lol. The lack of 4-jaw is half relieved, now; scored a new old stock Skinner 7" for a good price. If only it hadn't been packed loose in Styrofoam. So now I need a compressed air gun to clean it, and need to find or make a backplate for the bolt pattern (thru-face, four hole, recessed, with a large diameter register --pretty good setup)

The AXA QCTP works fine on the PM1228 once the turntable seat is modified.

Shipping the lathes with the wrong height on the turntable seat was an error made at the factory. Matt is having them modify the parts and will send them to anyone who purchased one of the affected lathes when he gets them.

The fix is simple. It took me about 30 minutes to remove the part mill it down and reinstall it, and that included cleaning all the waxy shipping oil off it.
 
The parts diagram and parts numbers of the 1228 also match the SIEG C8/C10 manuals. A few options like the motor are different, but largely the same machine. Which is fortunate because parts are available (my feed rod was turned off center)

Thanks for pointing that one one, I need to learn how to operate a web site and delete things!

The 1228 IS made by Sieg, yes. Not the 1127. The 1127 is neither Sieg or weiss, weiss does not build the machines.
 
Finally got my first 'thing' completed with the lathe! The backplate for my Skinner 4-jaw is now complete (at least, for now). Still lacking power feed, I used the compound and cross slide to face and square the disc, scribe the bolt circle for the drill press, and cut the 'register.' The register is probably a tiny bit loose (probably less than .001" clearance) but I have plenty of meat left to turn back the contact face and try again; they aren't kidding about how easy it is to go past the ideal 'snug fit' dimension (I actually think I bit myself by not letting the disc cool off after doing the bulk material removal for the register step; it was about 150deg or so, while the chuck was an ambient 95deg, and the interference between them smaller than I could measure or due to surface roughness). Anyway, I can finally do gun-barrel stuff now, at least to some level of accuracy, using the follow rest and compound, one little 4" section at a time (which is actually more productive than I'd thought it would be, though still rough on the fingers manually running the wheels)

Machine cuts real nice and smooth when you get that wonky feed rod bind out of the gear train. I'm honestly most happy that now I won't have to deal with machining cast iron again for hopefully, a long, long time...

Sounds like a good project, Tom. It is hard to sneak up on that last thousandth.

What's the plan with the feed screw? Is Matt getting another one for you?
 
We're working on it, and USPS is un-working on it. Have you gotten your tool holder or anything else, yet?
